Abstract

An energy absorption device in the form of a telescopic strut with two nesting tubes (10, 11) through which there is drilled a hole (12) in which there is received a pin (13). The tubes are of fibre reinforced plastic material whereas the pin is of stiffer material, such as, metal. When the strut gives way under a loading (P), the pin is forced to shear through the tube material.
